Engadget spotted some color e-paper at Ricoh's SID 2011 booth. The company is making some progress, but so far color e-paper doesn't seem too great.
The company's electronic paper, introduced at SID this week, promises to reproduce images that are 2.5 times brighter than competitors' offerings, while covering a color range that's four times wider. To achieve this, Ricoh used a simple lamination method, layering three strips of electrochromic material between two substrates. Unfortunately, however, there's no indication that the technology will be commercially available anytime soon, as Ricoh still needs to incorporate its e-paper onto more practical screen sizes, as well as enhance the display's durability -- both of which sound like pretty major hurdles to us.
